Change Placement Options of all PlacedItems

[Sayed Ali Mousawi]

Hi, i have a lot of Ai files that each one of them contains many placed items, and i need to change the Placement Option of them to preserve File Dimentions. is this options accessable via JavaScript?

Thank you very much.

var doc = app.activeDocument;

var myitems = doc.placedItems;

for (let i = 0; i < myitems.length; i++) {

    myitems[i]./*i don't know what*/    

}

it's probably not possible, not everything you can do in the UI is available to scripting.

you might need to do the adjustments yourself after updating the link

Hi @Sayed Ali Mousawi,

I have written a script that will return all placed items in a document to 100% size with the option to position in relation to the placed item's frame (eg. the clipping mask rectangle). Will that work in your case?
